The frontier editor stopped working . What happens when switch to Frontier Editor is that the left editor columns come up, but the content of the page does not appear, only the header module and sometimes footer module, but everything in between does not show up. Basically the page comes up empty on the Frontier Editor mode (it happnes at any page). The only option is left is to edit or create the page without using the Frontier Editor but basically this Frontier Editor is what makes this module useful. I had already licence, I thought maybe I need to renew my licence, I went ahead and bought the same module that used to work properly, but it did not solve the problem! It stopped working.
